Description

Die Erfindung betrifft ein Aluminiumblech zur Herstellung eines Architekturblechs, insbesondere Fassadenblechs, mit einer Kernschicht aus einer Aluminiumlegierung mit einer AIMg-Basis, insbesondere der AA5xxx-Serie, und mit mindestens einer auf einer Seite der Kernschicht walzplattierten Plattierschicht aus einer Aluminiumlegierung mit einer AIMg-Basis, insbesondere aus einer AA5005-AluminiumlegierungThe invention relates to an aluminum sheet for producing an architectural sheet, in particular cladding sheet, with an aluminum alloy core layer having an AIMg base, in particular the AA5xxx series, and having at least one aluminum alloy cladding layer coated on one side of the core layer with an AIMg base , in particular of an AA5005 aluminum alloy

Um bei Halbzeugen, nämlich Blechen, für Fassadenbleche eine hohe mechanische Festigkeit und dennoch eine gute Eignung für ein elektrolytisches Oxidationsverfahren zu schaffen, ist es aus dem Stand der Technik bekannt ( WO2010/144997A1 ), eine AA5083-Kernschicht, was zu den Aluminiumlegierungen mit einer AlMg-Basis zu zählen ist, mit einer AA5005-Plattierschicht, was zu den Aluminiumlegierungen mit einer AlMg-Basis zu zählen ist, zu versehen. Dennoch konnten bei derartigen Fassadenblechen vereinzelt Eintrübungen in der Eloxalschicht der AA5005-Plattierschicht festgestellt werden - was in weiterer Folge zu einem unbefriedigenden Glanzgrad führt. Zudem waren unter bestimmten Lichtbedingungen und Beobachtungswinkeln Farbreflexe zu erkennen, was nachteilig zu Veränderungen im Farbeindruck des Fassadenblechs führte. All diese Nachteile waren auch bei einer AA5205-Plattierschicht feststellbar, deren Si-Gehalt im Vergleich zur AA5005-Plattierschicht verringert ist.In order to provide a high mechanical strength and yet a good suitability for an electrolytic oxidation process in semi-finished products, namely sheets, for facade panels, it is known from the prior art ( WO2010 / 144997A1 ), an AA5083 core layer, which is to be counted among AlMg based aluminum alloys, with an AA5005 cladding layer, which is to be counted among AlMg based aluminum alloys. Nevertheless, occasional cloudiness in the anodization layer of the AA5005 cladding layer could be detected in such cladding sheets - which subsequently leads to an unsatisfactory degree of gloss. In addition, under certain lighting conditions and viewing angles, color reflections could be seen, which adversely affected changes in the color appearance of the cladding sheet. All of these drawbacks were also noticeable with an AA5205 cladding layer, which has a lower Si content compared to the AA5005 cladding layer.

Es ist daher die Aufgabe der Erfindung, ausgehend vom eingangs geschilderten Stand der Technik, ein Aluminiumblech mit Eloxalqualität zu schaffen, das einen hohen Glanzgrad und einen neutralen Farbeindruck sicherstellen kann.It is therefore an object of the invention, starting from the above-described prior art, to provide an aluminum sheet with anodizing quality, which can ensure a high gloss level and a neutral color impression.

Die Erfindung löst die gestellte Aufgabe hinsichtlich des Aluminiumblechs dadurch, dass die Plattierschicht 0,85 bis 0,95 Gew.-% Magnesium (Mg), 0,03 bis 0,06 Gew.-% Silizium (Si), 0,15 bis 0,20 Gew.-% Eisen (Fe), 0,08 bis 0,12 Gew.-% Kupfer (Cu), 0,08 bis 0,12 Gew.-% Mangan (Mn) und als Rest Aluminium sowie herstellungsbedingt unvermeidbare Verunreinigungen aufweist.The invention achieves the stated object with regard to the aluminum sheet in that the cladding layer contains 0.85 to 0.95% by weight of magnesium (Mg), 0.03 to 0.06% by weight. Silicon (Si), 0.15 to 0.20% by weight iron (Fe), 0.08 to 0.12% by weight copper (Cu), 0.08 to 0.12% by weight manganese ( Mn) and the balance aluminum and production-related unavoidable impurities.

Weist die Plattierschicht 0,03 bis 0,06 Gew.-% Silizium (Si), 0,15 bis 0,20 Gew.-% Eisen (Fe) und 0,85 bis 0,95 Gew.-% Magnesium (Mg) auf, kann trotz des vergleichsweise hohen Mg-Gehalts in der Plattierschicht deren Anteil an Fe- und/oder Si-haltigen intermetallischen Mg-Phasen niedrig gehalten werden, um die Ausbildung von Eintrübungen einer Eloxalschicht zu vermindern. Damit kann also unter anderem ein vergleichsweise hoher Glanzgrad des Architekturblechs sichergestellt werden. Zudem kann durch den niedrigen Si-und Fe-Gehalt auch deren Anteil in der Eloxalschicht gering bleiben, wodurch verminderte Streueffekte sowie unterwünschte Farbreflexe am Architekturblech vermieden werden können. Erfindungsgemäß können also nicht nur ein hoher Glanzgrad, sondern auch ein neutraler Farbeindruck gewährleistet werden, wodurch selbst über einen vergleichsweise breiten Blickwinkel der natürliche Farbton, der im Wesentlichen durch 0,08 bis 0,12 Gew.-% Cu und 0,08 bis 0,12 Gew.-% Mn der Plattierschicht bestimmt wird, ungestört zur Geltung kommen. Zudem kann durch den vergleichsweise geringen Mn Gehalt ein nichtrekristallisiertes, langgestrecktes Korngefüge und damit Störungen in der visuellen Gleichmäßigkeit der Oberfläche vermieden werden. Die Plattierschicht kann zudem als Rest Aluminium sowie herstellungsbedingt unvermeidbare Verunreinigungen aufweisen, ohne dass mit einer negativen Beeinflussung der vorstehend beschriebenen technischen Effekte zu rechnen ist. Im Allgemeinen wird erwähnt, dass die Plattierschicht Verunreinigungen mit jeweils maximal 0,05 Gew.-% und gesamt höchstens 0,15 Gew.-% aufweisen kann.If the plating layer has 0.03 to 0.06% by weight of silicon (Si), 0.15 to 0.20% by weight of iron (Fe) and 0.85 to 0.95% by weight of magnesium (Mg) In spite of the comparatively high Mg content in the cladding layer, their content of Fe and / or Si-containing Mg intermetallic phases can be kept low in order to reduce the formation of turbidity of an anodized layer. Thus, among other things, a comparatively high degree of gloss of the architectural sheet can be ensured. In addition, due to the low Si and Fe content, their proportion in the anodized layer can also remain low, as a result of which reduced scattering effects and undesired color reflections on the architectural sheet can be avoided. Thus, not only a high degree of gloss but also a neutral color impression can be ensured according to the invention, whereby even over a comparatively broad viewing angle the natural color shade, which is essentially composed of 0.08 to 0.12% by weight of Cu and 0.08 to 0 , 12 wt .-% Mn of the cladding layer is determined, undisturbed come to advantage. In addition, due to the comparatively low Mn content, an unrecrystallised, elongated grain structure and thus disturbances in the visual uniformity of the surface can be avoided. In addition, the cladding layer may contain aluminum as the remainder and impurities which may be unavoidable due to the production, without any negative effect on the technical effects described above. In general, it is mentioned that the plating layer can have impurities of not more than 0.05% by weight and not more than 0.15% by weight in total.

Im Allgemeinen wird erwähnt, dass als Architekturblech Bleche und/oder Bänder verstanden werden, die in der Architektur verwendet werden. Mit solchen Architekturblechen werden beispielsweise Fassaden von Gebäuden verkleidet, welche Architekturbleche in Folge auch meist Fassadenbleche genannt werden.In general, it is mentioned that the architectural sheet is understood to be sheets and / or tapes used in architecture. With such architectural sheets, for example, facades of buildings are clad, which architectural sheets in a row are also usually called cladding.

Im Allgemeinen wird erwähnt, dass vergleichsweise hohe Ansprüche zu einer Eloxalqualität an das Aluminiumblech gestellt werden können, wenn die Plattierschicht eine AlMgCuMn-Basis aufweist.In general, it is mentioned that comparatively high levels of anodization quality can be imposed on the aluminum sheet when the cladding layer has an AlMgCuMn base.

Als eine ausreichende Schichtdicke konnte bereits eine Plattierschicht mit einer Schichtdicke von 5 bis 20% an der Gesamtblechdicke des Aluminiumblechs erkannt werden.As a sufficient layer thickness already a cladding layer could be detected with a layer thickness of 5 to 20% of the total sheet thickness of the aluminum sheet.

Insbesondere 7 bis 15% Schichtdicke der Plattierschicht zeigten auffällig hohe Glanzwerte, wobei generell ein Anstieg der Glanzwerte bei dünneren Plattierschichten festgestellt werden konnte.In particular, 7 to 15% layer thickness of the cladding layer showed conspicuously high gloss values, with an overall increase in gloss values being found in thinner cladding layers.

Besonders hinsichtlich verschiedenster Anwendungsgebiete als Architekturblech kann sich ein Aluminiumblech mit einer Blechdicke von 0,5 bis 6 mm auszeichnen.Especially with regard to a wide variety of applications as an architectural sheet, an aluminum sheet with a sheet thickness of 0.5 to 6 mm can be distinguished.

Weist die Kernschicht 2,0 bis 2,5 Gew.-% Magnesium (Mg) auf, kann für eine ausreichende Festigkeit beim Architekturblech gesorgt werden. Zudem kann damit eine hohe Korrosionsbeständigkeit erreicht werden.If the core layer has 2.0 to 2.5% by weight of magnesium (Mg), sufficient strength can be provided for the architectural sheet. In addition, it can be achieved with a high corrosion resistance.

Das Aluminiumblech kann zudem eine vergleichsweise hohe mechanische Festigkeit aufweisen, wenn die Kernschicht aus einer AA5049-Aluminiumlegierung besteht. Des Weiteren kann solch eine AA5049-Kernschicht einen vergleichsweisen hohen Verwendungsgrad von Sekundäraluminium erlauben, wodurch Kostenvorteile bei der Herstellung des Aluminiumblechs erreichbar sind. Der Vollständigkeit halber wird erwähnt, dass als Sekundäraluminium Aluminium bzw. eine Aluminiumlegierung, gewonnen aus Aluminiumschrott, verstanden werden kann.The aluminum sheet may also have a comparatively high mechanical strength, if the core layer consists of an AA5049 aluminum alloy. Further, such an AA5049 core layer can allow a comparatively high utilization degree of secondary aluminum, whereby cost advantages in the production of the aluminum sheet can be achieved. For the sake of completeness, it is mentioned that as secondary aluminum aluminum or an aluminum alloy, obtained from aluminum scrap, can be understood.

Weist die Kernschicht beidseitig eine walzplattierte Plattierschicht auf, kann dies bei der Herstellung eines Architekturbleches vorteilhaft sein.If the core layer has a roll-coated cladding layer on both sides, this can be advantageous in the production of an architectural sheet.

Insbesondere kann sich die Erfindung dadurch auszeichnen, wenn das vorstehend angeführte Aluminiumblech als Architekturblech, insbesondere Fassadenblech verwendet wird, wobei die Plattierschicht mit einer Eloxalschicht versehen ist.In particular, the invention may be characterized when the above-mentioned aluminum sheet is used as architectural sheet, in particular cladding sheet, wherein the cladding layer is provided with an anodized layer.

Es ist zudem die Aufgabe der Erfindung, ein Verfahren zur Herstellung eines Architekturblechs, insbesondere Fassadenblechs zu schaffen, bei welchem enge Herstellungstoleranzen eingehalten werden können, um bei einem anschließenden Eloxalverfahren einen hohen Glanzgrad und einen neutralen Farbeindruck des Fassadenblechs sicherzustellen.It is also an object of the invention to provide a method for producing an architectural sheet, in particular cladding, in which close manufacturing tolerances can be met to ensure a high degree of gloss and a neutral color impression of the cladding in a subsequent anodizing process.

Die Erfindung löst die gestellte Aufgabe dadurch, dass das Kernblech mit einem Plattierblech aufweisend 0,85 bis 0,95 Gew.-% Magnesium (Mg), 0,03 bis 0,06 Gew.-% Silizium (Si), 0,15 bis 0,20 Gew.-% Eisen (Fe), 0,08 bis 0,12 Gew.-% Kupfer (Cu), 0,08 bis 0,12 Gew.-% Mangan (Mn), und als Rest Aluminium sowie herstellungsbedingt unvermeidbare Verunreinigungen walzplattiert wird.The invention achieves the stated object in that the core sheet with a cladding sheet comprising 0.85 to 0.95 wt .-% magnesium (Mg), 0.03 to 0.06 wt .-% silicon (Si), 0.15 to 0.20% by weight of iron (Fe), 0.08 to 0.12% by weight of copper (Cu), 0.08 to 0.12% by weight of manganese (Mn), and the remainder being aluminum as well Due to production unavoidable impurities is roll-plated.

Wird das Kernblech mit einem Plattierblech aus 0,03 bis 0,06 Gew.-% Silizium (Si), 0,15 bis 0,20 Gew.-% Eisen und 0,85 bis 0,95 Gew.-% Magnesium (Mg) walzplattiert, kann ein Verbundblech bzw. Fassadenblech mit konstanter Qualität erzeugt werden. Beispielsweise können dadurch Si, Fe und Mg in engen Toleranzgrenzen gehalten werden, wodurch eine eloxierte Plattierschicht einen hohen Glanzgrad und neutralen Farbeindruck aufweisen kann. Zudem kann durch das Verfahren Cu, nämlich von 0,08 bis 0,12 Gew.-%, und Mn, nämlich von 0,08 bis 0,12 Gew.-%, in der Plattierschicht eingestellt werden, was reproduzierbar den gleichen Farbton am Fassadenblech ermöglichen kann. Das erfindungsgemäße Verfahren kann damit reproduzierbar ein Blech mit besonders guter Eignung für ein anschließendes elektrolytisches Oxidationsverfahren schaffen.When the core sheet is coated with a clad sheet of 0.03 to 0.06 wt% of silicon (Si), 0.15 to 0.20 wt% of iron, and 0.85 to 0.95 wt% of magnesium (Mg ), a composite sheet or cladding sheet with constant quality can be produced. For example, Si, Fe and Mg can be kept within narrow tolerance limits, whereby an anodized cladding layer can have a high degree of gloss and a neutral color impression. In addition, by the method, Cu, namely, from 0.08 to 0.12 wt%, and Mn, from 0.08 to 0.12 wt%, can be set in the plating layer, reproducibly the same color tone at Facade sheet can allow. The method according to the invention can thus reproducibly create a sheet with particularly good suitability for a subsequent electrolytic oxidation process.

Im Allgemeinen wird erwähnt, dass besonders konstante Verfahrensverhältnisse erreicht werden können, wenn das Plattierblech eine AlMgCuMn-Basis aufweist. Hohe Glanzgrade am Architekturblech können durch das erfindungsgemäße Verfahren sichergestellt werden, wenn die Plattierschicht nach dem Walzplattieren eine Schichtdicke von 5 bis 20% an der Gesamtblechdicke des Aluminiumblechs aufweist. Insbesondere 7 bis 15% kann zu ungewöhnlich hohen Glanzgraden am Aluminiumblech führen. Im Allgemeinen wird weiter erwähnt, dass die Legierungen herstellungsbedingte je Verunreinigungen mit jeweils maximal 0,05 Gew.-% und gesamt höchstens 1 Gew.-% aufweisen können.In general, it is mentioned that particularly constant process conditions can be achieved if the cladding sheet has an AlMgCuMn base. High gloss levels on the architectural sheet can be ensured by the method according to the invention if the cladding layer has a layer thickness of 5 to 20% of the total sheet thickness of the aluminum sheet after roll cladding. In particular 7 to 15% can lead to unusually high degrees of gloss on the aluminum sheet. In general, it is further mentioned that the alloys may have production-related per impurities, each with a maximum of 0.05 wt .-% and a total of at most 1 wt .-%.

Das Verfahren kann in seiner Handhabung erleichtert werden, wenn das Aluminiumblech nach dem Walzplattieren eine Blechdicke von 0,5 bis 6 mm aufweist.The method can be facilitated in its handling, if the aluminum sheet has a plate thickness of 0.5 to 6 mm after roll-plating.

Weist die Kernschicht 2,0 bis 2,5 Gew.-% Magnesium (Mg) auf, kann das Walzplattieren erleichtert und damit die Reproduzierbarkeit des Verfahrens erhöht werden.If the core layer has 2.0 to 2.5% by weight of magnesium (Mg), roll cladding can be facilitated and thus the reproducibility of the process can be increased.

Die Verfahrenskosten können weiter vermindert werden, wenn ein AA5049-Kernblech mit einem Plattierblech walzplattiert wird, zumal die Kernschicht einen erhöhten Anteil an Sekundäraluminium zulassen kann.The process costs can be further reduced by roll-laminating an AA5049 core sheet with a clad sheet, especially as the core layer can allow an increased level of secondary aluminum.

Im Folgenden wird die Erfindung beispielhaft anhand eines Ausführungsbeispiels näher erläutert:The invention is explained in more detail below by way of example with reference to an exemplary embodiment:

Zum Nachweis der erzielten technischen Effekte wurden als Architekturbleche verschiedene Fassadenbleche hergestellt. Der walzplattierte Aufbau der untersuchten Fassadenbleche sind in der Tabelle 1 angeführt. Tabelle 1: Fassadenbleche Fassadenblech Kernblech Plattierblech 1 AA 5049 AA 5005 2 AA 5049 AlSi0,03Fe0,15Cu0,08Mn0,08Mg0,85 To demonstrate the technical effects achieved, various facade panels were produced as architectural panels. The roll-plated construction of the examined facade panels are listed in Table 1. Table 1: Facade panels facade sheet core sheet Plattierblech 1 AA 5049 AA 5005 2 AA 5049 AlSi0,03Fe0,15Cu0,08Mn0,08Mg0,85

Bei dem Fassadenblech 1 handelt es sich um ein AA5049-Kernblech, das mit einem herkömmlichen AA5005-Plattierblech einseitig walzplattiert wird. Zum Unterschied zum Fassadenblech 1 wurde beim Fassadenblech 2 das AA5049-Kernblech mit dem erfindungsgemäßen Plattierblech, aufweisend 0,03 bis 0,06 Gew.-% Silizium (Si), 0,15 bis 0,20 Gew.-% Eisen (Fe), 0,08 bis 0,12 Gew.-% Kupfer (Cu), 0,08 bis 0,12 Gew.-% Mangan (Mn), 0,85 bis 0,95 Gew.-% Magnesium (Mg) und als Rest Aluminium sowie herstellungsbedingt unvermeidbare Verunreinigungen, walzplattiert. Nach dem Walzplattieren lag die Schichtdicke der Plattierschicht um die 10% von der Gesamtblechdicke. Beide Halbzeuge mit je einer Gesamtblechdicke von ca. 4 mm wurden anschließend einem Eloxierverfahren unterworfen, um damit ein Fassadenblech zu schaffen.Façade panel 1 is an AA5049 core panel which is roll-formed on one side with a conventional AA5005 clad panel. In contrast to the cladding sheet 1, in the cladding sheet 2 the AA5049 core sheet with the cladding sheet according to the invention, comprising 0.03 to 0.06 wt.% Silicon (Si), 0.15 to 0.20 wt.% Iron (Fe) , 0.08 to 0.12 wt .-% copper (Cu), 0.08 to 0.12 wt .-% manganese (Mn), 0.85 to 0.95 wt .-% magnesium (Mg) and as Remainder of aluminum as well as production-related unavoidable impurities, roll-clad. After roll-plating, the layer thickness of the plating layer was about 10% of the total sheet thickness. Both semi-finished products, each with a total sheet thickness of about 4 mm, were then subjected to an anodizing process to create a cladding sheet.

Die fertigen Fassadenbleche 1 und 2 wurden schließlich auf ihre Eigenschaften hin untersucht. Hierzu wurden Glanzgrad sowie der Farbeindruck, der über einen Betrachtungswinkel von 1 bis 60 Grad gemessen wurde, mit Hilfe eines Farb- und Glanzmessgerät nach ISO 7668 unter einem Winkel von 60 Grad gemessen. Dies parallel zur Walzrichtung (RD) und senkrecht zur Walzrichtung (RD). Die erhaltenen Messwerte sind in der Tabelle 2 zusammengefasst. Tabelle 2: Messwerte Fassadenblech Glanzgrad parallel zur RD (ISO 7668) Glanzgrad senkrecht zur RD (ISO 7668) Farbeindruck 1 52 35 farbiger Schimmer 2 63 43 neutral The finished facade panels 1 and 2 were finally examined for their properties. For this purpose, the degree of gloss and the color impression measured over a viewing angle of 1 to 60 degrees were measured with the aid of a color and gloss meter according to ISO 7668 at an angle of 60 degrees. This parallel to the rolling direction (RD) and perpendicular to the rolling direction (RD). The measured values obtained are summarized in Table 2. Table 2: Measured values facade sheet Gloss level parallel to RD (ISO 7668) Gloss level perpendicular to the RD (ISO 7668) color impression 1 52 35 colored shimmer 2 63 43 neutral

Untersuchungen am Fassadenblech 2 zeigten, dass durch den eingestellten Si-, Feund Mn-Gehalt unter bestimmten Beobachtungswinkeln ein Auftreten eines farblichen Schimmers vermieden wird. Die natürliche, ins Gelb gehende Farbe (neutrale Farbe) des Fassadenblechs kam so bei unterschiedlichsten Lichtverhältnissen und Beobachtungswinkeln stets zur Geltung, was einen neutralen Farbeindruck sichergestellt.Investigations on the facade panel 2 showed that the occurrence of a colored glimmer is avoided by the set Si, Fe and Mn content under certain observation angles. The natural, yellow color (neutral color) of the facade sheet came in different lighting conditions and Observation angles always to advantage, which ensures a neutral color impression.

Daraus wird gefolgert, dass die erfindungsgemäße Zusammensetzung der Plattierschicht bzw. deren Eloxalschicht eine Streufarbe aufweist, die einerseits relativ nahe am Unbuntpunkt und anderseits relativ nahe an der Eigenfarbe - bestimmt durch den Cu und Mg Gehalt der Plattierschicht - liegt und damit keinen Einfluss auf die natürliche Farbe des Fassadenblechs nimmt. Gegenüber dem Fassadenblech 1 konnte so ein farblicher Schimmer vermieden werden, der sich am Fassadenblech 1 unter extremen Beobachtungswinkeln hin bis ins Grüne zog.It is concluded that the composition according to the invention of the cladding layer or its anodized layer has a diffuse color which, on the one hand, is relatively close to the chromatic point and, on the other hand, relatively close to the intrinsic color, determined by the Cu and Mg content of the cladding layer, and thus has no influence on the natural one Color of the facade sheet takes. Compared to the facade panel 1 could be avoided as a color glimmer, which moved to the facade panel 1 under extreme observation angles down to the green.

Zudem zeichnete sich das Fassadenblech 2 gegenüber dem Fassadenblech 1 mit einem erhöhten Glanzgrad aus, wie dies der Tabelle 2 zu entnehmen ist.In addition, the facade panel 2 was distinguished from the facade panel 1 with an increased gloss level, as shown in Table 2.
